A ...C- wv IMPROVEMENT IN' Pun/irs.

The Sehedulefefen'e. to in these Letters `Patent: and making part of the same.

`Be `it known that I, `l\[IeHArfn:. Ins'rrnn, of Waynesborough, Franklin county, Pennsyl vana, have invented a'new and useful Improvement in Force- Pumps; `and I do hereby declare that the following is a full and exact description thereof,`reference being had to the accompanying drawings, and to the letters of reference `marked thereon.

Figure 1 represents a sectional elevation, and

Figure 2, a similar view.

The same letters refer to corresponding parts.

My inventionfrelates to force-pumps, to be used for forcing waterout of deep"wells and cisterns to Ithe surface; and

, My-improvement consists in thev construction and arrangement ofthe several` parts of which it is composed, as hereinafter more fully described. To enable others skilled in the art `to make and use my invention, I will proceed to describe its construction and operation. i f Y t. i

A, in the drawings, represents the pump-barrel, which I propose to make of wood, of suitable length, and having any required bore;A The bore is to be uniform throughout its entireV length, save at the lower end, where it is to be' made slightly tapering, to receiverand retain the lower valve. Making the bore i thus uniform enables `me to withdraw from. it all the inner workingfparts, if it becomes necessaryto repair them, fromthe top ofthe well, and without necessitating the removal ofthe barrel therefrom.

l, B representsr tlieilower ordinary clack-valve, opening` upward. Its seat is made slightly tapering from top to bottom, and ts snugly in the lower' portion of the barrel.

staple or yoke, 1), is fastened to the upper end of the seat, by which it` may be removed from the barrel.

C represents the plunger, which is composed of the 'Lipper solid disk (fand` the lower portion or suction- `valve G, united together' by connectingfbars. The distance between the two portions is to be about equal tothe length of the stroke, and `its position in they pump-barrel, with referenoeto the discharge-pipe F,

` is to be such that in its reciprocating movement, the

solid upper disk G- sliall always be above and its valve `C always be below this dischargefpipe. The leather- `packing rings c' and c extend inwardly, a little distanoe beyond the disk C and valve-seat '0",so as to present each a `iange to the pressure of the water, by which means they are always kept tight 'until the leather wears out.

D is the piston-rod, which is attached to a pivoted lever, d, on top of the well, for operating the pump in the usual manner.

E represents the discharge-pipe above alluded to.

As a consequence of the peculiar construction Aof this pump, I am enabled to produce an effective one, well adapted for deep wells, which is simple in construction, cheap in first cost, and less liable to become deranged,than any pump with which I am acquainted.

The operation is as follows:

The 11p-stroke ofthe piston opens the lower valve, and water rushes into the barrel. By the down-stroke, the lower valve is closed, and the piston-valve opened, admitting the water into the piston until it reaches the upper solid disk thereof. If the stroke is not completed by this time, some of the water will be forced v What I` claim, and desire to secure lby Letters Pat- A pump, combining in its construction astraight barrel or stock, A, lower or check-valve `B, having a bail for, lifting vit out of its seat,a plunger, C, composed of an upper solid disk, C', connected to a valve, C", by bars, as shown, and a piston-rod, D, when all ,the parts are constructed and arranged, as andfor the 'purpose set forth.` i i In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
